I suppose it does reduce these stresses that while sBASIC has "strict" typing of variables, it allows easy transfer between variable types. It also has the concepts of undefined variables and defined but unset variables. Quite amazing for a language that fit in a very small part of 48K. -- Dave Park d...@sinclairql.com _______________________________________________ QL-Users Mailing List
